慢性化脓性中耳炎患者行鼓室成形术中植入钛人工听骨链在降低听力阈值及改善听力状态中的价值

Value of titanium artificial ossicular chain implantation in reducing hearing threshold and improving hearing status in patients with chronic suppurative otitis media undergoing tympanoplasty

摘要:

目的 探讨鼓室成形术中植入钛人工听骨链降低慢性化脓性中耳炎患者听力阈值、改善听力状态的效果。方法 选取河南科技大学第二附属医院耳鼻咽喉科2019年1月至2022年1月80例慢性化脓性中耳炎患者作为研究对象，随机数字表法分为对照组（40例）和植入组（40例）。对照组采取单纯鼓室成形术，进行自体听骨链重建，未植入钛人工听骨链，植入组患者在行鼓室成形术中植入钛人工听骨链，对比两组术前术后纯音听力重建水平，听力状态改善效果及并发症、复发率。结果 植入组听力改善有效率高于对照组（P<0.05）；术后听力阈值均较术前降低，且植入组气导听力阈值、气骨导差低于对照组（P<0.05），骨导听力阈值组间差异无统计学意义（P>0.05）；两组术后并发症发生率、复发率差异无统计学意义（P>0.05）。结论 在行鼓室成形术中植入钛人工听骨链能有效提升慢性化脓性中耳炎患者的听力水平，降低气导听力阈值及气骨导差，且不增加术后并发症及疾病复发风险，效果确切，值得临床应用及进一步研究。

Abstract:

Objective To investigate the effect of titanium artificial ossicular chain implantation in tympanoplasty on reducing hearing threshold and improving hearing status in patients with chronic suppurative otitis media.Methods Eighty patients with chronic suprurative otitis media treated in the Department of Otorhinolaryngology of the Second Affiliated Hospital of Henan University of Science and Technology from January 2019 to January 2022 were selected as research objects, and randomly divided into control group (40 cases) and implantation group (40 cases) by the method of number table. The control group received simple tympanoplasty and autologous osculus chain reconstruction without titanium artificial ossicular chain implantation. Patients in the implantation group were implanted with titanium artificial ossicular chain during tympanoplasty. The threshold values of bone conduction and air conduction hearing, air conduction difference, improvement effect of hearing status, complications and recurrence rate were compared between the two groups before and after surgery.Results The effective rate of hearing improvement in implant group was higher than that in control group (P<0.05). The hearing threshold after surgery was lower than that before surgery, and the air-conduction hearing threshold and air-bone conduction difference in the implantation group were lower than those in the control group (P<0.05), but there was no statistical significance in bone-conduction hearing threshold between the groups (P>0.05). There was no significant difference in the incidence and recurrence of postoperative complications between the two groups (P>0.05).Conclusion Implantation of titanium artificial ossicular chain during tympanoplasty can effectively improve the hearing level of patients with chronic suppurative otitis media, reduce the threshold of air conduction hearing and air bone conduction, and does not increase the risk of postoperative complications and disease recurrence. The effect is accurate, worthy of clinical application and further research.
